Answer 1

Hola Mate!!

Here's your answer:-

Diameter of the wheel = 84cm
So, radius of the wheel = 84cm/2 = 42cm
Circumference of the wheel =
$2 \times \pi \times r \\ = 2 \times \frac{22}{7} \times 42 \\ = 44 \times 6 \\ = 264cm$

4 revolution = 4 × 264 cm = 1056 cm = 10.56m
Speed of the car = 10.56m/s

Hope it helps
